The project won't be renamed, but it will be rebranded in the next few weeks. In the three years the project has existed I have only gotten two or three complaints about the mascot, but everyone has agreed that "Vagrant" itself is fine. Note that I've talked up to some pretty high levels of US government using Vagrant, and most are okay with it. One [fairly large/visible] organization within the US government has said they can't use it until the mascot is changed.
Vince the Vagrant is being retired.
